CONSTITUENTS of 1 THE UNIVERSE. 



assumed elements, we have the real key to the 

 whole of these changes. When the electrical 

 movement can in this identical way be made 

 to assume the motions called heat, and light; 

 we have this statement completely vindicated. 

 When, again, these motions are reversed, the 

 evidence is overwhelming. 



Special attention is here directed to the sig- 

 nificant fact that in all of these marked and 

 specific changes, nothing whatever is involved 

 but MOTION, DURING TIME, and IN SPACE. Mat- 

 ter, it will be clearly perceived, was not 

 involved in the least in these known oper- 

 ations. Inasmuch, then, as the imaginary 

 matter is so completely ignored and discredited 

 bv the action of these imponderables, and in 

 consideration of the fact that the supposed 

 ponderables, are after all, really imponderable 

 like the others, and knowing also that the im- 

 ponderables are only motion, what possible 

 ground is then left for the assumption that 

 there is any such thing as matter?
